An isolated particle of mass m is moving in horizontal in horizontal plane (x-y) along the x-axis at a certain height above the ground. It suddenly explodes into two fragments of masses m/4 and 3m/4. An instant later, the smaller fragment is at y = +15 cm. The larger fragment at this instant is at

An isolated particle is a single object that does not interact with external forces, allowing it to move freely in space. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25

A light string is wound round a cylinder and carries a mass tied to it at the free end. When the mass is released, calculate (a) the linear acceleration of the descending mass and (b) the angular acceleration of the cylinder and (c) the tension in the string. Show that the acceleration of mass is less than g.

Acceleration is the rate of change of velocity of an object over time, indicating how quickly it speeds up or slows down. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25
